I was there about a month ago, the water was around 50 - 80 meters from the trees. I believe the water capacity at the time was in the region of 45%, if Im not mistaken. Fishing was good, distance is key.
We fished the Carp SA'S there water is far back about 80m but you must go deep if you want decent fish...to the bridge side is the best...if you got a boat with fishfinder it will makew it easy for you
